I've tried several packages including ubuntugis but none helped. How to install qgis 3.x, more preferably qgis 3.4 lts in Ubuntu?

I've added following repos:: sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable sudo apt-get update

and then tried to install: but i get these errors::

$ sudo apt-get install qgis python-qgis qgis-plugin-grass

  • I doubt that anyone can help without you providing details. Assuming that this SHOULD work (and I see 3.4 listed on this page for ubuntugis) then this sounds more like a question on how you specifically sort out a specific problem you specifically are having. Without knowing what that problem is nobody can help. I'm making some assumptions here - I can think of some things you might have done wrong - but it's a long list and it wouldn't make sense to give an answer listing every possibility.

    Avoid ubuntugis, and take the ubuntu (not ubuntugis) version from the qgis repo.

    packages.ubuntu.com/bionic/qgis and launchpad.net/~ubuntugis/+archive/ubuntu/… have older versions, but qgis.org/ubuntu has the current QGIS 3.4.

The ubuntugis ppa holds only LTR versions, currently QGIS 2.18.28, see https://launchpad.net/~ubuntugis/+archive/ubuntu/ubuntugis-unstable/?field.series_filter=bionic.

If you want QGIS 3.4, you can take the https://qgis.org/ubuntu/ repository without any ubuntugis dependencies. You might have to remove any packages you have from ubuntugis before installing.

https://qgis.org/ubuntugis/ has support for bionic as well, but faced some issues recently. The QGIS packages are built against GRASS 7.4.3, but the ubuntugis ppa has meanwhile switched to GRASS 7.6.0. So I don't suggest that at the moment.

The situation is different for Xenial, because the main ubuntu repo for that does not include GDAL 2, which is mandatory for QGIS 3.

UPDATE

Ubuntugis unstable now has QGIS 3.4.14 for bionic.

  • So you're saying that the versions-installed/dependencies-required depend on the repo used? Would https://qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu be the most up to date location for which repo one might want? How might one determine the mismatch between versions like the one you knew about? (GDAL 2)

  • Yes, the site you linked is the best place to look for valid repo/version combinations. And the footnote qgis.org/en/site/forusers/alldownloads.html#id11 tells you about the GDAL2 limitation.

I had the same problem. What worked for me was mainly following this article, specifically:

1.Open /etc/apt/sources.list with

sudo nano /etc/apt/sources.list

2.If there is any mention of QGIS, delete that line. Then, copy there this line:

deb https://qgis.org/ubuntugis bionic main

3.Then, run this

sudo apt update && sudo apt-get install qgis python3-qgis qgis-plugin-grass

4.If it didn't work, go back to step 1 but instead of deb https://qgis.org/ubuntugis bionic main, try one of the following:

deb https://qgis.org/debian bionic main
deb https://qgis.org/ubuntu bionic main

Add the following PPA to your system manually by copying the lines below and adding them to your system's software sources (/etc/apt/sources.list):

For Bionic 18.04

deb http://ppa.launchpad.net/ubuntugis/ppa/ubuntu bionic main

deb-src http://ppa.launchpad.net/ubuntugis/ppa/ubuntu bionic main

Then do an update,

sudo apt-get update

And then install

sudo apt-get install qgis python3-qgis qgis-plugin-grass

This is what worked for me after struggling to install QGIS3.x on ubuntu

Cheers!

i had a similar problem on manjaro. i needed to install any dependencies manually. on ubuntu you could install the dependencies via synaptic, i assume. a workaround for your problem could be the official flatpak package for qgis - only if installing qgis via repository or ppa keeps failing. there should be installing guides on the qgis homepage and/or flathub.
